NAME

6       pptp_selinux - Security Enhanced Linux Policy for the pptp processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the pptp processes via flexible manda‐
10       tory access control.
11
12       The pptp processes execute with the pptp_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep pptp_t
19
20
21

ENTRYPOINTS

23       The pptp_t SELinux type can be entered via the pptp_exec_t file type.
24
25       The default entrypoint paths for the pptp_t domain are the following:
26
27       /usr/sbin/pptp
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       pptp policy is very flexible allowing users to setup  their  pptp  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for pptp:
40
41       pptp_t
42
43       Note:  semanage  permissive  -a  pptp_t can be used to make the process
44       type pptp_t permissive. SELinux does  not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least  access  required.   pptp
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run pptp with the tightest access possible.

PORT TYPES

167       SELinux defines port types to represent TCP and UDP ports.
168
169       You can see the types associated with a port  by  using  the  following
170       command:
171
172       semanage port -l
173
174
175       Policy  governs  the  access  confined  processes  have to these ports.
176       SELinux pptp policy is very flexible allowing users to setup their pptp
177       processes in as secure a method as possible.
178
179       The following port types are defined for pptp:
180
181
182       pptp_port_t
183
184
185
186       Default Defined Ports:
187                 tcp 1723
188                 udp 1723
189

MANAGED FILES

191       The  SELinux process type pptp_t can manage files labeled with the fol‐
192       lowing file types.  The paths listed are the default  paths  for  these
193       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

239       SELinux requires files to have an extended attribute to define the file
240       type.
241
242       You can see the context of a file using the -Z option to ls
243
244       Policy governs the access  confined  processes  have  to  these  files.
245       SELinux pptp policy is very flexible allowing users to setup their pptp
246       processes in as secure a method as possible.
247
248       STANDARD FILE CONTEXT
249
250       SELinux defines the file context types for the pptp, if you  wanted  to
251       store  files  with  these types in a diffent paths, you need to execute
252       the semanage command  to  sepecify  alternate  labeling  and  then  use
253       restorecon to put the labels on disk.
254
255       semanage fcontext -a -t pptp_var_run_t '/srv/mypptp_content(/.*)?'
256       restorecon -R -v /srv/mypptp_content
257
258       Note:  SELinux  often  uses  regular expressions to specify labels that
259       match multiple files.
260
261       The following file types are defined for pptp:
262
263
264
265       pptp_exec_t
266
267       - Set files with the pptp_exec_t type, if you  want  to  transition  an
268       executable to the pptp_t domain.
269
270
271
272       pptp_log_t
273
274       -  Set files with the pptp_log_t type, if you want to treat the data as
275       pptp log data, usually stored under the /var/log directory.
276
277
278
279       pptp_var_run_t
280
281       - Set files with the pptp_var_run_t type, if you want to store the pptp
282       files under the /run or /var/run directory.
283
284
285
286       Note:  File context can be temporarily modified with the chcon command.
287       If you want to permanently change the file context you need to use  the
288       semanage fcontext command.  This will modify the SELinux labeling data‐
289       base.  You will need to use restorecon to apply the labels.
290
291

COMMANDS

293       semanage fcontext can also be used to manipulate default  file  context
294       mappings.
295
296       semanage  permissive  can  also  be used to manipulate whether or not a
297       process type is permissive.
298
299       semanage module can also be used to enable/disable/install/remove  pol‐
300       icy modules.
301
302       semanage port can also be used to manipulate the port definitions
303
304       semanage boolean can also be used to manipulate the booleans
305
306
307       system-config-selinux is a GUI tool available to customize SELinux pol‐
308       icy settings.
